Description
Technical field
The utility model belongs to auto electric field, refers to a kind of automobile bond terminal especially.
Background technology
The power supply in auto electric field divides positive pole and negative pole, the negative pole of automotive wire bundle is cellular type terminal, with bolt and nut, this cellular type terminal and car body panel beating (or vehicle frame) are linked togather, be called for short bonding terminal, battery terminal negative is also received on panel beating (vehicle frame) by which, and such car body panel beating (vehicle frame) has just become public negative pole.Bonding is generally the synonym in automobile circuit, and so-called bonding is exactly link together with the current-carrying part of car body.The cathode conductor of automobile we be usually referred to as ground strap.
In order to ensure that bonding is reliable when existing bonding terminal assembling, using before assembly and manually first the paint at bonding termination contact panel beating (vehicle frame) place being wiped off, then assemble bonding terminal, also will smear vaseline protection after installing bonding terminal, prevent from getting rusty.
On automobile, ground strap is the part forming automobile circuit loop, and plays a very important role.The each loop of automobile circuit forms loop by car load bonding, finally flows into battery terminal negative.
Automobile bond is reliably the precondition ensureing that auto electric is working properly, and bad earth can cause all kinds of electric fault.
Along with automobile function gets more and more, automobile circuit system becomes increasingly complex, and on car load, bonding numbers of terminals also gets more and more, and bonding terminal is fixedly the important step of automobile production assembling.
Current traditional ground structure is copper sheet type bonding terminal, and as shown in Figure 1, bonding terminal 1 is exactly a copper sheet, then copper sheet there is circular hole, afterbody is crimping structures of copper lines, and arranges a serrated lock washer 3, is fixed on vehicle frame or car body panel beating through after circular hole and serrated lock washer 3 by bolt 2.
The fixed form of tradition bonding terminal realizes panel beating by serrated lock washer to scrape paint, and bonding terminal and nut are separate type.That generally scrapes that paint realizes bonding position by additional sawtooth chip architecture to panel beating scrapes paint.
The shortcoming of tradition bonding terminal is:
1, after scraping paint operation by serrated lock washer, bonding terminal contacts with vehicle body sheet metal, and bonding terminal powers on to flow through to scrape and paints the panel beating at position, then gets back to battery terminal negative.Once it is bad to scrape paint, will conducting, cause electric fault.
2, after increasing serrated lock washer between vehicle body sheet metal and bonding terminal, contact resistance can be increased.
3., bonding terminal, serrated lock washer, nut each other structure be separated, mounting process relative complex, property easy to assembly is not good enough, and efficiency of assembling is low.
4, transmission bonding terminal and plate contact-making surface are plane as shown in Figure 2, in assembling process, desirable assembling scheme ensures that reverse side contacts with panel beating plane (or serrated lock washer), front press against bolt, can ensure that the contact of reverse side and panel beating plane (or serrated lock washer) is fitted like this.But reality is, because traditional bonding terminal assembling has unpredictability, can there is front laminating panel beating, the situation that reverse side press against bolt occurs, and this kind of situation usually occurs in assembling process, when this happens, following problem can be caused to occur:
1) when the urgent power of bolt is too small, due to the first Influential cases A and the second Influential cases B at bonding terminal ends crimping position, there is upper-lower height difference, bonding terminal and panel beating (or serrated lock washer) cannot be fitted completely, easily cause loose contact and increase contact resistance, causing electric fault.
2) and in the urgent process of bolt, automobile factory adopts the urgent moment of bolt standard (or when urgent moment is excessive) of normal regulation, bonding terminal tails 4 meeting flexural deformation, bonding terminal after distortion ensure that the laminating completely of contact-making surface, but bonding terminal reliability can be damaged, for the later stage leaves potential safety hazard.
Thus, when bonding terminal is counter fill time, can potential safety hazard be there is, and bonding terminal itself cannot avoid this kind assembling situation generation.
5., when the normal specification of traditional bonding terminal is assembled, compression bonding terminal is to serrated lock washer surface to need artificial firmly (direction of power is perpendicular to panel beating surface), and make both moment holding surface fit-states, this causes assembling process to waste time and energy.
